make error about kimera-vio HOT 10 CLOSED

Thank you for your answer. DBoW2-v1.1-free was used in my system. I used the latest code and solved the error. In addition, I find a little error with gcc-5.4.
Kimera-VIO/tests/testStereoVisionFrontEnd.cpp:401:38: error: ‘isnan’ was not declared in this scope
EXPECT_TRUE(isnan(s.second.uR()));
Replace isnan with std::isnan will be more robust.

@yunzc did you see this error before?

Hi @cumtchenchang could you tell us what versions of gtsam and opengv you are using and also the cmake configurations for gtsam? Another thing that might be worth trying is to toggle the march-native flag in gtsam, seems like it causes some problems for gtest on some systems

from kimera-vio.

@yunzc GTSAM = 4.0, opengv=1.0. cmake3.14 for gtsam. I will try your suggestion. Thank you.

@cumtchenchang any update? We haven't been able to reproduce your issue.

from kimera-vio.

Closing for now.

@cumtchenchang if this is still an issue, try the latest master.

Also, try installing the libparmetis-dev package (sudo apt-get install libparmetis-dev). We were able to reproduce a similar error, which was solved by installing this dependency.

Updated installation instructions in 69519e5.

@ToniRV Thank you for your suggestion, the original issue is still on. Because of China's National Day, I am sorry that I did not update in time. I will follow @marcusabate 's suggestion and update it soon. Thank you.

@marcusabate Thank you for your help. I followed your suggestion and solved the original issue. But a new error occurred.

In addition, I checked dependencies by

sudo apt-get install -y cmake.
However, the error is still on. Thank you.

@cumtchenchang good to hear the suggestion worked, at least partly.

DUtils::Random::RandomInt comes from the DLib library which was once a dependency of DBoW2. Since Kimera uses DBoW2 for loop closure detection, you're seeing the missing dependency there.

However, The DLib dependency was removed from DBoW2 a while back in this commit.

I'm guessing you may have an older version of DBoW2 installed that is still inking to the DLib library. Can you tell me what commit you are using on DBoW2 and that DLib is not referenced in the CMakeLists.txt of your local clone of DBoW2?
